“The worlds of different peoples have different shapes. The very metaphysical presuppositions differ: space does not conform to Euclidean geometry, time does not form a continuous unidirectional flow, causation does not conform to Aristotelian logic, man is not differentiated from non-man or life from death, as in our [Western] world. We know something of the shape of these other worlds from the logic of native languages and from myths and ceremonies. . .”
